Ocean Alkalinization

Ocean alkalinization involves adding substances like crushed minerals to seawater to increase its pH and buffering capacity. This process enhances the ocean's ability to absorb carbon dioxide (CO₂) from the atmosphere, helping mitigate climate change. When minerals dissolve, they react with CO₂, forming stable compounds that are stored in the ocean. This not only reduces the greenhouse gas levels but also can counteract ocean acidification, which harms marine life. Ocean alkalinization is a promising nature-based approach that leverages Earth's natural processes to enhance carbon sequestration while supporting ocean health.
